Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dual-bearing reel, and more particularly to a dual-bearing reel suitable as a trolling reel in which a spool shaft is supported at a substantially central portion of a reel body.

[0002]

2. Description of the Related Art As one type of a dual-bearing reel, a large fishing reel called a trolling reel is known. The trolling reel includes a spool around which the fishing line is wound, a spool shaft that supports the spool, and a reel body that supports the spool shaft at a central portion thereof. The reel body is provided with a handle shaft which is disposed so as to protrude outside in parallel with the spool shaft, and has a handle fixed to the end. A transmission mechanism for transmitting rotation from the handle shaft to the spool is provided between the handle shaft and the spool, and a drag mechanism is provided between the transmission mechanism and the spool.

[0003] The reel body usually has a pair of disk-shaped lid members and a cylindrical member disposed between the lid members.
Although there is a piece structure, there is also a two-piece structure in which a cover member is provided only on the handle shaft mounting side and the opposite cover member and the cylindrical member are integrated. In any case, the lid member on the handle side and the cylindrical member are connected and fixed by screws. The spool shaft is supported by both lid members in the former case, and is supported by the lid member and the cylindrical member in the latter case. The handle shaft is rotatably supported by the lid member. The transmission mechanism is disposed between the lid member and the cylindrical member, and has a main gear mounted on the handle shaft, and a pinion gear connected to the drag mechanism. The drag mechanism has a disk connected to the pinion gear, a friction plate provided on the spool so as to be relatively non-rotatable, and a drag operation lever for moving the spool shaft in the axial direction to contact the friction plate with the disk. ing.

[0004]

It is on the handle side that the force is strongly applied by the operation of the angler such as the drag operation lever and the handle. That is, in this type of reel, a force acts between the fishing rod and the handle with the mounting portion on the fishing rod as a fulcrum. For this reason, in the conventional configuration, a strong stress acts on a connecting member such as a bolt for connecting and fixing the cover member on the handle side and the cylindrical member regardless of the structure of the reel body. Therefore, it is necessary to increase the strength of the connecting portion. In order to increase the strength of the connecting portion, conventionally, measures such as increasing the diameter of the connecting member used for connection and increasing the number of connecting members have been taken. Increasing the diameter of the connecting member increases the diameter of the cylindrical member, which leads to an increase in the size of the reel body. Further, if the number of connecting members is increased, the diameter of the cylindrical member can be kept as it is, but the number of connecting members handled at the time of assembling work or the like increases, and such work becomes complicated.

[0005] It is an object of the present invention to maintain the strength of the reel body on the handle side and not to increase the size and number of connecting members to be handled.

[0006]

A dual bearing reel according to a first aspect of the present invention includes a spool around which a fishing line is wound around an outer periphery, a spool shaft, a reel body, a handle shaft, a handle, and
A transmission mechanism. The spool shaft supports the spool. The reel body has a lid member supporting one end of the spool shaft at a substantially central portion thereof, and a lid member supporting the other end of the spool shaft at a substantially central portion thereof, and the lid member is fixed by a connecting member, and is integrally formed of the same material. And a bottomed cylindrical frame portion. The handle shaft is disposed so as to protrude outside the frame portion in parallel with the spool shaft, and is rotatably supported by the frame portion. The handle is fixed to a protruding end of the handle shaft. The transmission mechanism transmits the rotation from the handle shaft to the spool.

In this dual-bearing reel, since the lid member and the frame portion are connected on the side opposite to the handle mounting side of the reel body where little force acts, it is not necessary to increase the size and number of the connecting members. In addition, since the handle mounting side is the bottom of the bottomed cylindrical frame unit integrally formed of the same material, a connecting portion is not required, and the strength of the reel body on the handle mounting side is maintained high.

A dual bearing reel according to a second aspect of the present invention is the reel according to the first aspect, wherein the frame portion has a cylindrical portion accommodating a spool therein, and a portion of the outer peripheral portion is radially expanded from the cylindrical portion. A non-circular portion having a protruding bulging portion, and bulging radially from the minimum inner diameter portion of the cylindrical portion to accommodate a part of the transmission mechanism inside the bulging portion of the non-circular portion. A convex space is formed. In this case, even if a part of the transmission mechanism has a size larger than the outer diameter of the spool, they are housed in the convex space, so it is not necessary to increase the outer diameter of the cylindrical portion. .

A dual-bearing reel according to a third aspect of the present invention is the dual-bearing reel according to the first or second aspect, wherein the transmission mechanism relates to a drag mechanism for transmitting rotation of the handle shaft to the spool by a frictional force, and the drag mechanism for detachment. And an operating mechanism for changing the frictional force between the two. In this case, transmission of rotation of the spool in the line winding direction and braking of rotation in the line feeding direction can be realized by one mechanism.

The dual bearing reel according to a fourth aspect of the present invention is the dual bearing reel according to the third aspect, wherein the transmission mechanism includes a main gear mounted on an end of the handle shaft opposite to the protruding end, and a main gear mounted on the spool shaft. And a pinion gear supported and fixed to the drag mechanism. A dual bearing reel according to a fifth aspect of the present invention is the dual bearing reel according to the fourth aspect, wherein the main gear has two large and small gear plates, and the transmission mechanism selectively transmits rotation of the handle shaft to one of the gear plates. And a selection mechanism for performing the selection. In this case, the spool can be rotated at two speeds.

A dual bearing reel according to a sixth aspect of the present invention is the reel of the fifth aspect, wherein the two gear plates are housed in a convex space, and are coaxial with a fitting member disposed between the two gear plates. The gear plate on the reel body side of the two gear plates can be fitted so as to be disposed, and is coaxial with a bearing provided on the reel body so as to rotatably support the handle shaft. It can be fitted to be placed. In this case, the two gear plates are housed in the convex space, and even if the handle shaft cannot be inserted into the bearing in a state where the two gear plates are attached to the handle shaft, the two gear plates cannot be inserted into the bearing. The transmission mechanism can be easily assembled by fitting the handle shafts through them after fitting the gear plates concentrically.

The spool 3 has a body 3a and flanges 3b integrally formed at both ends of the body 3a. A sound output gear 35 is provided on an end surface of the left flange portion 3b. An engagement claw 36 supported by a C-shaped spring member 37 attached to the side plate 10 is engaged with the sounding gear 35, and a click sound is generated when the spool 3 rotates. A friction plate 26 constituting the drag mechanism 7 is fixed to the end surface of the right flange portion 3b of the spool 3 so as not to rotate relatively.

As shown in FIG. 2, the handle 4 is fixed to a protruding end of a tubular handle shaft 5 disposed below the spool shaft 2 and parallel to the spool shaft 2. Handle shaft 5
Is rotatably supported on the reel body 11 by a flanged bush 39 at a second boss 11e. The bush 39 protrudes from the reel body 11 and extends outside. The bush 3 is fastened with the nut 41 screwed into this protruding end.
9 is fixed to the reel body 11. Handle shaft 5
A slit 5a penetrating up and down is formed at the tip, and a female screw 5b is formed at the inner surface of the tip.

The gear transmission mechanism 6 includes a first gear 16 for high-speed winding and a second gear 17 for low-speed winding rotatably supported by the handle shaft 5, and a state in which these gears 16 and 17 are engaged with each other. A third gear 18 and a fourth gear 19 rotatably supported by the spool shaft 2 with the first and second gears 1
6 and 17, and the handle shaft 5 is coupled to the engagement piece 20 for transmitting rotation, and two compression springs 21a and 21b for positioning the engagement piece 20 on both sides of the engagement piece 20;
And an operation shaft 22 for setting the position of the engagement piece 20.

As shown in FIG. 3, the first gear 16 and the second gear 16
The gear 17 has a cross-shaped engaging groove 16a, 17
The engaging piece 20 is locked in one of the engaging grooves 16a, 17a. Further, between the second gear 16 and the second gear 17, a fitting ring 40 having step portions 40a and 40b on both sides is arranged. The facing surfaces of the second gear 16 and the second gear 17 are provided with engagement grooves 16a, 1
Steps 16b, 17b (in FIG. 3, 17b
(Shown only) are formed therein, and the step portions 40a and 40b of the fitting ring 40 are loosely fitted to the fitting ring 40 by a stainless steel joint. Further, a step 16c is formed on a surface of the first gear 16 opposite to the facing surface. A bush 39 for supporting the handle shaft 5 is provided on the step 16c.
The flange end face 39a (FIG. 2) is loosely fitted by a stainless steel joint.

As described above, by providing the fitting ring 40 to enable the first gear 16 and the second gear to be joined together by air, and by enabling the first gear 16 and the bush 39 to be able to be joined together by air, the two The gears 16 and 17 and the bush 39 can be arranged concentrically with respect to the reel body 11. Therefore, when the two gears 16 and 17 are attached to the handle shaft 5 first, even if the two gears 16 and 17 interfere with the reel body 11 and the handle shaft 5 cannot be inserted into the bush 39, the reel A bush 39 fixed to the body 11 has two gears 16 with a fitting ring 40 interposed therebetween.
17 are successively fitted, and they are arranged concentrically. Thereafter, an assembly including the handle shaft 5, the operation shaft 22, and the engagement piece 20 is inserted into the bush 39, so that the gear in the convex space R is formed. The work of assembling the transmission mechanism 6 is facilitated.

The engagement piece 20 is provided with the slit 5 of the handle shaft 5.
It is non-rotatably arranged in a. At the center of the engagement piece 20, a projection 20a is provided movably in the axial direction by a flange-like attitude holding member 24 screwed to the tip of the handle shaft 5. By supporting the protruding portion 20a with the posture holding member 24, it is difficult for the engaging piece 20 to tilt in a direction along a plane including the axis of the handle shaft 5 when the engaging piece 20 moves in the axial direction. A spring receiving member 25 for receiving the compression spring 21a is integrally formed on the outer peripheral side of the posture holding member 24.

The operation shaft 22 penetrates through the handle shaft 5 and projects outside. The operation shaft 22 is
A guide portion 5b screwed into a protruding end of the handle shaft 5 is supported so as to be movable in the axial direction. A groove 22a is formed at the protruding end of the operation shaft 22 to the outside. This groove 2
The handle 4 is provided with a slide-type stopper 23 that engages with 2a. Further, a spring receiving member 22b that receives the compression spring 21b is provided at the opposite end of the operation shaft 22.

The fourth gear 19 has a ratchet pawl 34 for preventing the spool shaft 2 from rotating in the reverse direction (rotation in the line feeding direction). The drag mechanism 7 is shown in FIG.
As shown in FIG. 5, a disk 27 pressed against the friction plate 26,
A drag operation mechanism 14 for moving the spool shaft 2 together with the spool 3 in the axial direction.

The disk 27 is connected to the third and fourth gears 18,
It is non-rotatably mounted on a transmission member 28 connected to the transmission member 19. The transmission member 28 is rotatably supported on the spool shaft 2 by a bearing 41. The drag operation mechanism 14 includes a rotation screw 30 screwed to an end of the spool shaft 2 on the handle 4 side, a cam body 29 abutting on the rotation screw 30, and a first boss portion of the cam body 29 and the reel body 11. And a drag lever 31 disposed between the end lever 11d and the end face. The cam body 29 is arranged coaxially with the spool shaft 2, and has a cam surface 29 a that is in contact with the drag lever 31 on the side opposite to the surface in contact with the rotation screw 30. The drag lever 31 is swingably supported by the first boss 11d, and a cam surface 31a is formed on a contact surface with the cam surface 29a. The cam surfaces 29a and 31a are of a riding type, and when the drag lever 31 swings, the spool shaft 2 slides in the axial direction with respect to the reel body 1.

Next, a method of operating the trolling reel will be described. When performing high-speed winding by the gear transmission mechanism 6, first, as shown in FIG. 1, the operating shaft 22 is pulled out. Thereby, the engagement piece 2 is pressed by the urging force of the compression spring 21a.
0 engages with the engagement groove 16a of the first gear 16. As a result, the rotation of the handle 4 is controlled by the handle shaft 5 and the first gear 1.
6, transmitted to the spool 3 via the third gear 18, the transmission member 28, the disk 27 and the friction plate 26, and the spool 3 rotates at high speed.

On the other hand, when winding at low speed, the operating shaft 22 is pushed in as shown in FIG. Thereby, the compression spring 2
1b, the engaging piece 20 is engaged with the engaging groove 17 of the second gear 17.
a. As a result, the rotation of the handle 4 causes the handle shaft 5, the second gear 17, the fourth gear 19, the transmission member 28,
The power is transmitted to the spool 3 via the disk 27 and the friction plate 26, and the spool 3 rotates at a low speed. If the stopper 23 is engaged with the groove 22a when the operation shaft 22 is pushed in, the pushed state of the operation shaft 22 is maintained. For this reason, even if the phases of the engagement piece 20 and the engagement groove 17a do not match, the state where the engagement piece 20 is in contact with the side surface of the second gear 17 is maintained. The biasing force of the compression spring 21b causes the engagement piece 20 to
a.

When the frictional force of the drag mechanism 7 is adjusted, the position of the spool shaft 2 in the axial direction is appropriately set by the rotation knob 30 and the drag lever 31 is operated. When the spool shaft 2 is moved toward the handle 4, the spool 3 moves toward the disk 27, resulting in an increase in frictional force. Conversely, when the spool shaft 2 is moved to the side opposite to the handle 4, the spool 3 moves in a direction away from the disk 27, so that the frictional force is reduced. Then, when the friction plate 26 of the spool 3 is completely separated from the disk 27, the reverse rotation of the spool 3 is permitted.

The handle 3 allows the spool 3
When the reel is rotated in the winding direction, or when the drag mechanism 7 is operated by the fish and the spool 3 reverses, a large force acts on the handle 4 side of the reel body 1. However, in this embodiment, since the handle 4 side of the reel body 1 is integrated, the strength is maintained high. Further, since the side plate 10 and the reel body 11 are fastened on the opposite side of the handle 4, the number of fixing screws 8 can be reduced, and the size can be reduced.

Further, even when the distance between the outer peripheral portions of the first and second gears 16 and 17 of the gear transmission mechanism 6 and the spool axis is larger than the diameter of the spool 3, a convex space R is provided by the Is stored, there is no need to increase the outer diameter of the connecting portion 11c. Further, in a conventional dual-bearing reel in which two members (a lid member and a cylindrical member) of a reel body are connected on the handle side, when a large force is applied, the connecting portions of the two members are displaced, so that the two members are misaligned. In addition, a spool touch phenomenon in which the spool shaft is displaced and the spool contacts the reel body easily occurs. However, in the present embodiment, since the two members are connected on the handle side and on the opposite side, even if a large force acts on the handle side, the force hardly acts on the opposite side. For this reason, even if there is a play in the connection portion, the two members are hardly misaligned, and the spool touch phenomenon is less likely to occur. Therefore, thread biting due to the spool touch phenomenon is unlikely to occur.

[Other Embodiments] (a) Instead of a trolling reel, the present invention can be applied to a normal double bearing reel provided with a drag mechanism on a handle shaft. (B) The present invention is also applicable to a trolling reel in which a spool shaft rotates and a trolling reel in which a drag mechanism is disposed on the side opposite to the handle side.

[0033]

According to the dual-bearing reel of the present invention, since the lid member and the frame portion are connected on the side opposite to the handle mounting side of the reel body where little force acts, the size and number of the connecting members are reduced. There is no need to increase. In addition, since the handle mounting side is the bottom of the bottomed cylindrical frame unit integrally formed of the same material, a connecting portion is not required, and the strength of the reel body on the handle mounting side is maintained high.
